A post on Facebook confirms that British-born Hunnam, best known for his roles in Pacific Rim, Queer as Folk and Sons of Anarchy, will take on the role, following months of speculation about who the part would go to.

Fifty Shades weirdly began life as Twilight fan fiction by author E. L. James before she rewrote it, got it published, and it became a huge hit. It's been called "Mommy Porn" by some, due to its mature and erotic themes and the perception that it is popular among older women.

What do you reckon? Will Hunnam be able to handle the transition from Jaegers to bondage, and is Johnson right for the role? Let us know your thoughts in the comments.
